TO ALL TO .WHOM THESE I'RESENxTS'IMAY COME: V g

vBe it known that I, MARCUS L. M. HUsssY, of thecity of New York, in the county and State of New York, have'invented a new and'useful Scale for Postal and other Purposes, and thatthc following is a full and exact description thereof', reference being' had to the drawing herewith accompanying.

Figure l is a front view of my invention, l Y

Figure 2 is a side view of the same, and Figure 3 is a sectional view`thercot'. l h 1 The objectof `my invention is to provide a scale which,whc'n used for postal purposes, shall indicate not only the wcig'ht'of the letter or packageV submitted to it, 'bnt'shall also correctly determine -the cost oftrans mitting the said letter or package to any and all countries'betwecn which and the Uuitcd States postal relations vmay exist, by any and all established mailroutes; and, to enable others skilled in the art te manufacture my' invention, I will proceed to describe the same.. j

Within the tube a, which may be mounted upon legs, or suspended from the ceiling, or attached to the wall, I confine the spring b, the upper end of which I attach to the cap c of the tube a, and the lower end of which spring I fasten to. the rod d. V To the lower end of the rod' d, I suspend the platform e, while to theupper end of said rod is 'attached Athe arm f, holding the adjustable indicator o. .This indicator or pointer is rendered adjustable by having itsshanl: passed through the eye :,formed in the arinf, where it isliirmly secured in any desired position by the regulating-screw g.

To show more clearly the uses to which this .indicator is applied, it is proper to describe the dial represented by the drawings.'A To the exterior of the tube a there is secured a stud, x, terminatingn a centre-pin, h, which pin projects from lthe centre of the face of 'said stud. Centred upon this pin is a revolving dial, i, formed of thick paper, metal, or other suitable material, which dial may be held in position by the pressure of the tightening-nut 1c, working upoua screw cnt upon the centre-pinln` The dial i, when used for' postal purposes, may be laid off, on either .or both sides, in the following manner: From the inner circle, marked m on the accompanying drawings, are drawn radiating lines n n n n n, extending from said inner circle to the periphery of the dial. These lines are intcrsrected by circles concentric to the circle m. These circics represent the distance travelled by the indicator or pointer o, as successive ounces or fractions of ounces are laid on the suspended platform c, the movement of the pointer being occasioned by the elongation of the springb when the weight'is applied.; Near the peripheryof the-dial aretwo circles, between which, in spaces formed-by thc radial lin'es and intersecting circlesi'is marked the rate ofpostageon pamphlets and newspapers. Between these two -outer circles and the system'ofcircles described as representing ounces and fractions of ounces occurs a space, in which space, n'od between the radiall lines, are marked the names of countries and postal routes, and following these, toward the centre of the dial, there is marked: in the spaces formed by the radial lines and the intersecting circles, thcysum required for the payment of letter-postage, as indicated hy the movement ofthe pointer 0,. according to the amount of weight placed on the platform e.

The pointer or indicator o is constructed of metal, or other suitable material, and may be made in the form .of nfork, with one prong of said fork pass/ing on either side of the dial i, when said dial is arranged with lines,

circles, and names of countries and routes on both sidnsthcreof, or maybe made with a single point `when one face only of said dial is so arranged, the point or points tcrminating,\vlicn no weight is on the platform, pre. ciscly at the rst or outer circle, t, ofthe system of circles described as representing ounces and fractions of ounces. The upper end of this double or single'ponter or indicatore terminates in a. rod or shank, which passes through thc eye s, in the armf, whereit is secured by the set-screw g, and readily adjusted to exactly moet the liuc t, incase of a derangement of the spiral spring b, by contraction or cxpansioii'undcr a varying temperature,

or from any other cause, it having been found in practice that, when thc scale is balanced, with thc point at thelinc t, tho pointer will indicato with absolute accuracy, throughout the entire system of circles, the weight applied. l v "he necessity for a dial, with its multitude of divcrging lines, in connection with the other features of this device, is occasioned by the very large number of countries with which tls-,e United States maintains postal relations, 'and the still larger numb'er of postal routes having varyiu'roi` rat'cshof postage. For postal purposes, therefore, the dial is deemed indispensabler Forv ordinary weighing purposes, however, a section or segment-of the dial may be employed," ufion which, in contiguous radiating. lines, niay be indicated, by appropriate intersecting lines, t'he minute subdivisionsof troy, apotlicearies?, and avoirdupois weight.

What I claim as new, and desire to secure by-Letltcrs Patent of the United States, is- 1. The revolving dinl', upon which are inscribed mail-routes and postal rates, substantiallyI as described and for thc purposes-specied. C v i 2. The combination ofthe revolving dial z', upon Vwhich are inscribed postal rates animan-routes, wit-liA theV spring, or other equivalent \\'eigliing-balance,' substantially as and for the purpose described.

3. The combination of the dial or a seffncn't thereof, Awith the adjustable indicator o, when constructed substantially as described.' 1, I i

f1. The vertical indicator, when used'in contraction with a revolving dial, or a segment thereof,Y for tiic purposes specified. 5

5. ihe vertical indicator, in connection witlr :'i. spiral-spring balance, fortlie' purposes specified. MARCUS'L. M. HUSSEY.
